new cisco ip video phone?
Hi,
Just finished watching the season finale of '24' the TV series.
Throughout the series they have been showcasing Cisco hardware
especially Cisco IP phones (7970's).
On the last episode or two they showed what seemed to me a new cisco
IP video phone. It stands just as a 12" lcd screen with the cisco
branding/logo and letters just as the 79xx series.
I wonder if this is a

S100U == DEAD !
We have a S100U which we were using as our sole internal phone
extension.
Today it died.
Picking up the phone now results in a brief dialtone followed by bursts
of random static and crackling noises and then a second or two of
fast-busy followed by silence and more crackling noises.
I've tried the hardware attached to a couple of different machines as
well as a couple of different phones.

Wine 1.1.7: Sound regression?
I have recently formatted my system in order to install Intrepid Ibex, and I am now using it with Wine 1.1.7. I did a backup of the prefixes of the games I was using in Hardy / Wine up to 1.1.5, and imported them in my new installment. The games work normally, but the sound is crackling all the time for each of them; something which was not happening in my former installment. I have not noticed

IAX Inbound Sound Quality
I have a couple of DID's through VP Connect and have been having sound
quality issues on incoming calls. During the call, the calling parties
voice sometimes sound like it is crackling, in other words it is not
very crisp. I would liken it to listening to a radio with a blown
speaker. This sound defect comes and goes throughout the call. The
other person is always audible but it just isn't

Echo and crackle
We are running asterisk with a single POTS line for local calls and a

line it is more than likely, but not always, going to have significant
distracting echo. In addition to that there is occasional heavy crackle
or static. I have tried to follow the guidelines at :

Problem compiling chan_sccp
Hi,
I recently bought a 7910. I found out too late that it would not do

original chan_sccp driver and having 80% functionality with this
model.

TDM400 audio problems
Sorry everyone, I know this has been hashed over a bunch of times but I
can't find anything that pertains to specific cracking and popping on the
FXO modules of a TDM04. This happens on inbound or outbound calls. This is
the first install I have done with a TDM card for FXO modules so please, be
kind if I am missing something really simple.

Audio popping in OggDS
Hi all,
I'm experiencing problems with the OggDS filters. The main one is that when I
play back an audiovideo OGG file (2 x stereo audio track, one played at a time)
the sound is popping and crackling continuously. I thought it was buffer
starvation but it was not. Even if I save to wav the decompressed vorbis track
it contains the popping. It is very audible.
Is it a known problem?

Opus for speech: VBR vs CBR
Hi guys,
I'm using Opus for speech in wide-band mode (sampling rate 16000) and 20ms
frames with signal type set to SIGNAL_VOICE.
I have a few questions here:
1.
When I choose VBR mode, the codec seems to choose the bitrate on its own.
However, that seems to be an issue on mobile devices. In some cases, when I
configure the bitrate to say 20kbps, I see that the outgoing codec bitrate

zaptel huge irq problem
Hello,
I had noticed strange crackling sound on my phone calls going through my
zaptel device (TDM400P), so i decided to check on possible timer issue,
and found lots of issues on forums concerning the sensibility of zaptel
with IRQs, and tried about everything: moving PCI slots, noapic and
acpi=off boot options, play with different kernel options:
